Meu laptop de trabalho é, infelizmente, um Macbook Pro. Seu controlador Bluetooth é um Broadcom BCM20703A1 [05ac: 8290], que, se eu estiver entendendo isso corretamente, faz parte da mesma placa que o wifi, um BCM43602 [14e4: 43ba].
Meu problema: o dispositivo Bluetooth é detectado; no entanto, hcitool scan , ou a coisa da barra de rede do gnome, não consegue encontrar nenhum dispositivo parável. Eu posso emparelhar meu telefone Android com meu fone de ouvido, mas nenhum deles aparece no Debian. O log às vezes mostra isso nas tentativas de scan ou inq :
Bluetooth: Inquiry failed: status 0x12
O módulo wifi, brcmfmac , me dá uma mensagem de erro interessante (se não for um arenque vermelho):
brcmfmac 0000:03:00.0: firmware: direct-loading firmware brcm/brcmfmac43602-pcie.bin

brcmfmac: brcmf_inetaddr_changed: fail to get arp ip table err:-23
Aparentemente, a falta do arquivo brcmfmac43602-pcie.txt é algo chamado de "nvram", que devo descartar. De acordo com os documentos , ele deve estar em /sys/firmware/efi/efivars/nvram* , mas eu não tenho esse arquivo ( efivars está montado).
Eu não tive sucesso pesquisando na web. O que devo fazer?
Estou executando o Debian stable (stretch) e obtive os mesmos resultados com o kernel 4.9.0-5 e com o 4.14.0-0 de stretch-backports. Tentei atualizar firmware-brcm80211 , firmware-{linux,misc}-{free,nonfree} e bluez-firmware packages de backports, mas isso não ajudou.
